MLGetReal64()

gets a double-precision floating-point number from the MathLink connection link and stores it in x.

Details

If the data on the link corresponds to a C int, MLGetReal64() will coerce it to a double before storing it in x.

If the data on the link corresponds to a number outside the range that can be stored in a C double on your computer system, then MLGetReal64() will fail, and return 0.

Arbitrary-precision real numbers are transmitted between MathLink programs as the number sequence generated by RealDigits, typically as an integer array or as a C string of decimal characters. This sequence can be read using MLGetInteger32List() or MLGetString().

MLGetReal64() returns 0 in the event of an error, and a nonzero value if the function succeeds.
